准备工作
1.IOS 、TFTP server 、Console 线缆、直通/交叉线缆。
注：低端交换机2950/3550/3560中，可供升级使用的IOS 有两种，一种是后缀为.bin 的，一种是为.tar 的。.bin 为IOS 文件，而.tar 是一个归档（压缩）包，内含.bin 的IOS 和web 管理使用的HTML 静态页。如下图 文件备份

上传文件
3.
如果不需要web功能，仅上传.bin的IOS即可: 3560G-A#copy tftp: flash:
Address or name of remote host []? 192.168.1.88
Source filename []? c3560-ipservicesk9-mz.122-55.SE1.bin
Destination filename [c3560-ipservicesk9-mz.122-55.SE1.bin]?
附1：如flash 不够大，删除旧IOS 之后不慎进入switch ：模式，可按照以下步骤恢复：
Switch ：flash_init Switch ：load_helper
Switch ：copy xmodem ：flash ：c3560….bin Begin the Xmodem or Xmodem-1K transfer now …超级终端【传送】【传送文件】Switch ：boot
Destination filename [c3560-ipservicesk9-mz.122-55.SE1.bin]?

如需使用web 功能，需上传.tar 整个归档。.tar 归档的上传可通过Cisco Network Assistant 软件方便地实现，也可通过CLI 的方式。使用CNA 的前提是交换机含有支持web 界面的HTML 文件，这里我们只介绍CLI 的方式:
3560G-A#archive download-sw /leave-old-sw tftp:192.168.1.88/c3560-ipservicesk9-mz.122-55.SE1.tar /leave-old-sw 表示保留原IOS 归档，也可以使用/overwrite 覆盖原IOS 归档。修改引导变量
4.3560G-A(config)#boot system flash:/c3560-ipservicesk9-mz.122-5
5.SE1.bin 3560G-A#show boot
BOOT path-list : flash:/c3560-ipservicesk9-mz.122-55.SE1.bin
验证是否升级成功5.3560G-A#write
[OK]
3560G-A#reload
#重启时可观察屏幕输出或重启后通过show version 来验证IOS 是否升级成功，再尝试运行OSPF/BGP#
附2：如上传并修改引导变量后，仍使用旧IOS 引导，可尝试使用以下命令:（未验证）3560G-A(config)#boot boothlpr flash:/c3560-ipservicesk9-mz.122-55.SE1.bin 或
Switch:set boothlpr flash:/c3560-ipservicesk9-mz.122-55.SE1.bin
Switch：copy xmodem：flash：c3560 (i)
Begin the Xmodem or Xmodem-1K transfer now…超级终端【传送】【传送文件】
Switch：boot Switch:set boothlpr flash:/c3560-ipservicesk9-mz.122-55.SE1.bin
